Background/Purpose: Thoracoscopic excision of pulmonary nodules is often required for diagnostic or therapeutic purposes, however subpleural and sub-centimeter nodules can be difficult to visualize. Various CT-guided localization techniques have been described, though there is minimal published pediatric data regarding the use of microcoils. We hypothesize that microcoil localization facilitates thoracoscopic resection of pulmonary nodules in children. Methods: A multi-institutional retrospective review of children who underwent preoperative CT-guided localization of lung nodules was conducted from 2012 to 2019. A combination of methylene blue dye (MBD), wires, and microcoils were utilized for CT-guided localization. When microcoils were utilized, fluoroscopy assisted in lesion identification and resection. Results: Eighteen patients (mean age 13 years, range 2–21 years) underwent thoracoscopic resection of 24 preoperatively localized pulmonary nodules. Mean size and depth of the lesions were 5.5 mm and 10 mm, respectively. Microcoil placement was successful 95% of the time and assisted in lesion localization in 88% of cases. Wire localization was not a durable technique, as 3 of 5 wires became dislodged upon lung isolation. Conclusions: Preoperative CT-guided localization with microcoils can assist in fluoroscopic-guided resection of pulmonary nodules in children. This technique avoids the pitfall of wire dislodgement, and provides surgeons an additional technique to localize sub-centimeter, subpleural nodules. Type of Study: Retrospective Review. Level of Evidence: Level III.
